[2008] Scientific paper: Opportunistic Distance-aware Routing in Multi-Sink Mobile Wireless Sensor Networks

Abstract: Wireless Sensor Networks are a research area of growing importance within the Wireless Networks research community. One of the major issues in this area is the search for efficient routing methods. Most of the routing algorithms developed so far are limited to single-sink scenarios with no or limited mobility. This paper presents a new routing approach, ODEUR (Opportunistic relative Distance-Enabled Unicast Routing), that is targeted to Sensor Networks with mobility-induced intermittent connectivity and multiple alternative sinks as it is often seen in wildlife or habitat monitoring applications.

[2006] Context Routing in Wireless Sensor Networks

Abstract: Routing in ad-hoc networks selects the optimal path to send a message from a source to a sink. Optimal path does not always refer to an optimal routing in WSNs. To extend maximum network lifetime, the context information must be considered as most important feature (for example, energy awareness). Here, we step into context routing analysis of WSN. Context awareness answers computational power questions about WSN requirements and limitations.

Thesis: "Opportunistic Routing in Multi-Sink Mobile Ad Hoc Wireless Sensor Networks (ORMMA-WSN)" Presentation, Report
This thesis introduces the opportunistic routing and analyzes a new algorithm for Wireless Sensor Networks - a new routing technique for ad hoc mobile multi-hop wireless networks.
The routing algorithm is created based on a mobility scenario. The network consists of multiple nodes and multiple sinks. All of them are mobile. A source node generates data packets, which must be routed to the nearest sink. Sinks send high power periodic beacon packets. When nodes move, the received signal strength of the received beacon packet changes. Nodes calculate their mobility direction according to this difference of power levels. Then these beacons are forwarded to the neighbor nodes with normal power. Data packets are routed according to the obtained mobility information, such as mobility gradient, neighborhood availability. According to this knowledge, an efficient direction of data packet routing is predicted. Decision is done by every node which participates in the routing process. In other words, each node evaluates the opportunity of packet handling to the neighbor nodes.
The opportunistic routing algorithm is implemented and simulated in the OPNET simulator. The model is built on top of a partly implemented IEEE 802.15.4 model.
Implementation of non-beacon, unslotted CSMA/CA medium access layer is part of this work.
The comparison of results is done with respect to the AODV routing protocol. An AODV model was implemented as hybrid structure of IEEE 802.15.4 MAC and AODV routing over IP.
The scope of the analysis is energy consumption, end-to-end delays and goodput of the opportunistic routing protocol.

Thesis: "Embedded Web Server. Design and Implementation"

Areas of application of embedded Web servers can be of any choice. Theoretically we can connect all electronic equipment to the global network. Measurement, environment monitoring, control hardware, data collection devices can be equipped with this network interface. For example, a coffee machine can include a Web server inside to monitor quantities of coffee, milk, sugar, etc., call for service. Another project could be collecting information about temperature, moisture and pollution amount in certain city or country regions from embedded hardware sensors. Wireless technologies enable the scalability and independence of wired limitation. Just set your imagination free..
